Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If cell material is continuously pumped through an arrangement of two electrodes in a reaction vessel, then the cell material can be treated with electric pulses, but non-uniform flow and electric field profiles are formed resulting in heterogeneous treatment conditions

Engineering Contradiction:
Improvecell treatment throughputVSAvoidhomogeneity of treatment conditions
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies the dynamics principle by rotating the treatment vessel or electrode arrangement during electric pulse application. This rotational movement dynamically changes the position of cell material relative to the electric field, ensuring that all regions of the cell material experience uniform electric field exposure over time, thereby resolving the contradiction between continuous processing and treatment homogeneity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces a temporal dimension to the treatment process by applying electric pulses in sequential cycles while rotating the vessel. This transforms a static spatial problem into a dynamic temporal-spatial process, where different spatial positions are exposed to the electric field at different times, achieving overall uniformity through multi-dimensional coordination.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a flow profile is formed between the wall and the center of the reaction vessel, then continuous processing is enabled, but deviations with respect to process conditions occur over the vessel diameter

Engineering Contradiction:
Improvecontinuous processing capabilityVSAvoidconsistency of process conditions
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

By implementing rotational movement of the treatment vessel or electrodes, the patent converts the static flow profile problem into a dynamic system where different radial positions are sequentially exposed to the electric field. This ensures that despite continuous flow and associated velocity gradients, all cell material ultimately receives consistent treatment dosage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs periodic electric pulse application combined with continuous rotation, creating a cyclic treatment regime where each portion of cell material experiences multiple pulses at different orientations. This periodic action compensates for flow-induced variations and ensures reliable, consistent treatment conditions throughout the continuous processing operation.

Inventive Principle:
Principle #19Periodic action
